Two hands / linked blocks / no speed target
Find the moving joint before making the next fold.
Compact state: eight blocks form a 2 × 2 × 2 cube. Illustration; compare your actual joints with its maker’s instructions.
Check which cube you have
An infinity cube changes shape because small blocks are linked. A Fidget Cube keeps a rigid body and has separate controls. If yours has buttons and a joystick, use the six-face lesson.
Start with both hands
Work over a clear surface. Support the blocks from underneath, leaving room for the linked sections to swing. Look for an actual hinge or flexible connection across a seam; a visible gap alone does not identify a folding axis.
Use an intact eight-block model with its own opening demonstration. Jo Nakashima’s paper model below explains the changing shapes; its paper joints do not establish the force or exact grip for a plastic or metal model.
Read the sequence: compact → open → change axis → compact
The aim is to recognize a moving pair and support the remaining blocks. “Open left” is not a universal instruction: rotating the whole object changes left and right.
01
Locate the opening shown for your model
Hold the compact cube loosely in both hands. Match a visible joint and the surrounding block arrangement to the maker’s starting view. Support each moving section, with fingers clear of the seam that will close.
Check: you can point to the connection that will bend. If you only see a gap, rotate the whole cube to inspect it before trying a fold.
02
Open around that joint
Guide the linked sections around their connection, following the demonstrated direction. Keep supporting the blocks as they spread; do not pull them away from each other. In the selected paper demonstration, the compact form opens into a flatter arrangement.
Check: the connection stays together and the sections move without catching. Pause if a neighboring block blocks the path; extra pressure does not find the right axis.
03
Pause flat, then find the next axis
At the flat state, count two rows of four blocks in one layer. Reposition your fingers underneath. Follow the next connected pair in the demonstration: the next fold uses a different joint. Do not try to bend the whole rectangle through an unhinged seam.
Check: all eight blocks remain linked. To reset instead of continuing, reverse the motion you just made along the same joint.
04
Let the next pair fold into the compact form
Guide the next linked sections together along their joint while supporting the rest. Allow the blocks to settle into the compact 2 × 2 × 2 arrangement; the colors or faces showing may have changed. Regrip before starting another cycle.
Finish: stop at a stable position with every connection intact. There is no required speed, color pattern or number of repetitions.
Count the blocks before looking for the next joint. The closed and open illustrations show the two arrangements; they are separate generic concepts, not frames of one tested object.
The video supplies the transition between states. A surface seam in this picture does not tell you which way to bend your own cube.
Watch the linked blocks / 0:14–0:28
See the compact shape open and change its folding axis.
Origami creator Jo Nakashima demonstrates his eight-block paper infinity cube before the construction tutorial. Watch the short opening demonstration for the changing arrangement, then pause before trying your own model.
Near 0:15: the small blocks form a compact cube, supported by both hands.
Near 0:20: the blocks spread into a two-row, four-column arrangement.
Near 0:25: the hands reposition and another connected section folds over.
Pause at each change
Find which connection is bending and which blocks the other hand supports. If your model has a different hinge arrangement, use its own demonstration for the movement order.

What interrupted the fold?
I cannot find the opening
Rotate the whole object and compare its joints with the maker’s starting view. A compact-shape illustration cannot locate every hinge. Do not insert a tool into a seam to find an opening.
It stops halfway
Pause and check for a finger or neighboring block in the path. Return along the motion that was free. If it still catches without obstruction, stop and use the exact model’s support instructions.
I reached a rectangle and do not know what comes next
Support it flat and find the next joint in the demonstration. You can reverse your last fold to return to the known starting state. You do not need to force a new fold to complete an attempt.
A joint is loose, torn or separating
End the exercise and keep any loose pieces together. Paper, pinned plastic and metal joints need different repairs. This lesson does not prescribe tape, glue or lubrication for an unknown construction.
One attempt, one useful observation
First identify a joint, make one free fold, pause and reverse it. Then follow your model’s demonstration through the next axis. Record the state where you paused and whether the same path returned freely.
Success: you followed a visible connection, kept all blocks linked and stopped without forcing a joint. A smooth cycle is a later result, not a prerequisite for a useful first attempt.

Read the hinge before moving the block
Original concept diagram. Generic example; not a product photograph.
The inset isolates two blocks and their pivot. It does not map every hinge in an eight-block infinity cube or prescribe its folding order.
What to do next
Find the actual joints on your model and follow its maker’s full opening-and-return demonstration. Leave room for connected blocks before beginning.
When to stop
If the next direction is unclear or the joint catches, stop. Do not pull blocks apart or infer a force limit from this picture.
What are you trying to decide?
Mechanism
The named Grey Duck Labs model is described as eight linked cubes. Its changing shape is different from the individual controls on a six-face Fidget Cube.
Next: Compare with the Fidget Cube control map if the names are confusing.
Surface
A texture description concerns the exterior. It does not establish hinge clearance, folding force or durability.
Next: Record the exact texture but leave unreported mechanical fields unknown.
A stuck fold
Do not force an unfamiliar hinge path. This review has no verified repair or force limit for the model.
Next: Use the maker’s instructions or support for the exact object.
Two objects can look like a cube while moving in entirely different ways. A linked-block mechanism needs room for the blocks to move. A picture of the closed shape cannot establish the motion path or the space needed around it.
A texture choice is only one field
Keep surface preference separate from construction and hinge behavior. We have not compared the textures in hand, and a product option name is not a measured grip or comfort result.
Making one is a separate project
A commercial model listing is not a reusable build license. We do not provide a copied model or promise that a paper prototype behaves like this object. Any future build page needs its own files, permission record and physical acceptance.

Maker listing describes eight linked cubes and surface variants; no wear, force or sound test.
Full evidence boundary and review method
Manufacturer sources were reviewed September 23, 2026; the Cube reference and Spinner sources were checked September 25. The Spinner guide also cites a named independent hands-on author. We checked model names and the fields shown here, kept missing fields unknown and wrote the decision paths as editorial suggestions. Original diagrams are explanatory illustrations, not product photos or physical test evidence. This guide is not a product ranking or a verified physical lesson. External links identify sources; availability can change.
These optional self-reports stay in this browser tab. Reading, trying an action, receiving a file and making a project are different outcomes; none is independently verified. Nothing is sent to the site.
